Hi
I am about to skim coat large areas of plaster board . In regard to controlling suction should I wet the walls first. Also can I do a wall area 3 metres long in one go ?
Thanks
Huw
Answer
Plasterboard is low suction and generally does not need any suction control, however if you are in a very warm environment and the plasterboards have been in place a while, or need to ensure you have maximum time to work the plaster then a coat of PVA will seal the surface and ensure you have plenty of time.
It is hard to comment on the area that you will be able to manage as everyone has different abilities but always practice upon a smaller area first. When attempting larger areas remind yourself of the aim of each stage so that no time is wasted in doing something that is not important.
